Yes, I recently found some Heatons (oddly enough) and probably two Cairos in my area.
They are not easily found by us, but every now and then you can come across something nice, like the Akro shooter that I found about 15 days ago
Heaton/Cairo
Yes,...in the past they were called Alley patch, (with that blue spot, but the base was covered with moss) as they were found in fair quantities at the Alley site, later known to be Akro.
The base of this is transparent cobalt blue and from the long and rather linear seam, (penultimate photo) to me it might be cac, but it's all questionable
